To all! whom it may concern:

Be it known that I, Aucusrus C. CAREY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Messachusetts, have invented a certain new and useful Improvement in Drying-Machines, of which the following is a full, clear, and exact description.

In newspaper-printing ollices using stereotypeforins on rotary or cylinder presses and where the work of stereotyping is done in a hurry it is customary to cast the stereotypeplates and then rapidly cool them by iininersion in water and then dry them reparatory to fixing them on the cylinder of t 1e printingpress. Any water remaining on the plates is apt to so spoil the inking-rollers as to mar the \im ressions. It is usual to take out inkingloss of rollers.

ml ers thus defaced and substitute perfect ones, and this involves loss of time as well as Were the plates perfectly dried in the first instance and before being mounted upon the cylinder, there would be no such loss, and hence it is quite desirable to provide means for drying the inside and outside faces of the plates as they are taken from 7 the cooling-bath. Hand-wiping is not only slow and uncertain, but it is a t to deface any half tones or other process illustrations included in the forms. I have found that these without injur T by machinery containing a revolving brus for acting upon the concave inside or back of the plates and an absorbent roll for acting upon the convex outside or printing-face of the plates.

The invention consists of a plate-support, a rotary brush for drying the back, and a swinging roll for drying the face organized in a hand or power machine, so that the late may be thoroughly dried before it is p aced upon the cylinder.

The invention is herein shown as embodied in a hand-operated machine; but it is not thus limited.

In the accompanyin drawings, illustrating the invention, in tie several figures of which like parts are similarly desi nated, Fi ure 1 is a side elevation showing t e outsife wi ingroll in two ositions by full and dotted ines, respectively. Fi 2 is a front elevation and artial section, t e lane being indicated by t e dotted line 2 2, Fig. 1. Fig. 3 is a side elevation and partial section of part of the up or support for the plate.

I will now escribe one form of the invenric or other material which will readil tion which is in use, but mean not thereby to be limited to the construction and arrangement of parts shown, since obviously these may be varied within the principle of the invention so as to meet the requirements of various printing'ofiices.

The machine may he mounted upon a bench, table, or stand of suitable construction (not shown) over a drip pan (not shown) arran ed to conduct away the water removed by t e apparatus from the stereo ty i e-plates.

wo uprights 3 are provided, and these are connected y sta rods 4 to constitute a frame which is a apted to receive a shaft 5, suitably equipped with an desired mechanism, such as a crank-hen le 6, for rotating same. On this shaft is secured a rotary brush, here shown as comprising heads 7,fast on the shaft, and on these heads are fixed the brushes 8, of bristles or other suitable materia Mounted loosely upon the shaft 5 are arms 9, connected by any suitable number of sta rods 10 to constitute-a swinging frame. '1 e arms are slotted longitudinally at 3.1 to receive adjustable brackets 12, in which is mounted a pad-roll 13. g This pad-roll is pref erably constructed of a. s indie 14, having on it heads 15, between w ch are clamped a number of disks 16 of some absorbent material, such as cheese-cloth or other textile fail};-

a sorb water. This pad-roll is mounted inits brackets, so as to be readil removable when the rolls become saturate and it is neces sary to replace them by d rolls while the wet rolls are being dried for rther use. The brackets 12 embrace the arms 9 and arcadjustable longitudinally of the slots 1i by means of setscrews 17 engaging them, and the adustrnent may be fixed by means of clam olts 18. The object in making the brac ets adjustable is to secure the requisite pressure of the pad-roll upon the stereotypeplates.

The brush is arran ed to be turned to the left, Fig. I, and in order to prevent its 0 posite rotation a ratchet 19 is provided on 3 ft 5, and the direction of rotation of the ratchet, and consequentl the shaft, is controlled b a pawl 20, pivote upon the ad'acent uprig t.

The stereotype plate 21 0 common construction is supported at its lower end in brackets 22, mounted in longitudinally-adjustable stands 23, erected upon the machine-support. The u per end of the storetype-platc is supported upon a bar or other suitable device 24, having )ins 25, Fig. 3, and mounted in arms 26, which are secured to the uprights 3.

After the stereotype-plate has been cast and cooled by dipping it in water, as usual,it is placed upon the brackets 22 with its upper edge resting a ainst the pins 25, its upper end being OVCITJELlSLIlOBd, as indicated in Fig. 1, so that its concave side will be next to the brush. The pad-roll is then drawn over the u per edge of the plate, so as to hold the p ate firmly in place. The brush then being rotated to the left, Fig. 1, will sweep over the surface of the plate and carry down the water with it, and the agitation of the air incident to the rotation of the brush will further serve to thoroughly dry the concave or inside of the late. By swinging the padroll-carrying ffame downward the pad-roll will be rolled over the type or convex side of the plate under sufficient pressure to thoroughly absorb all of the water or moisture on that side of the plate. By resting the upper ,edge of the plate against the pins space is left at that point for the escape of the water and the circulation of air.

In Fig. l the pad-roll is shown in full lines at the beginning of its movement over the plate and is shown in dotted lines at the end of its drying motion. The movement of the pad-roll over the plate may be repeated as often as necessary. The brush carries down the water before it and the pad-roll absorbs the water, and whatever drip there is falls into the pan beforementioned, but not shown, and is conveyed away.

By the construction described I have provided a very simple, durable, and effective means for thoroughly and rapidly drying stereotype-plates, especially t ose used in news aper-offices.

W at I claim is 1. A drying-machine, comprising a platesupport, a frame, a rotary brush mounted on said frame and adapted to act on the concave or inside of a stereotype-plate arran ed upon said support, and a swinging absor ent roll also mounted on said frame and adapted to be passed over the convex or printing side of said plate.

2. In a drying-machine, the combination of uprights, a rotary shaft mounted therein, a brush on said shaft, means to rotate said shaft, a swinging frame mounted on said shaft and a pad-roll carried b said frame.

3. In a drying-machine, t e combination of uprights, a rotary shaft mounted therein, a brush on said shaft, means to rotate said shaft, a swim ing frame mounted on said shaft, 3. pad-r51 carried by said frame, and a support for the stereotype-plate.

4. A drying-machine, comprising essentially a frame, a rotary shaft supported in said frame, a brush on said shaft, means to limit the rotation of said brush in one direction only, a frame mounted to swing on the shaft independently of its rotation, a padroll carried by said swinging frame, and means to support a printing-plate between the brush and the pad-roll.

5. A dryingmachine, comprising essentially a frame, a rotary shaft supported in said frame, a brush on said shaft, means to limit the direction of rotation of said brush, a frame mounted to swing on the shaft independently of its rotation, a pad-roll carried y said swingin frame, means to adjust the pad-roll in said ame, and means to support a printing-plate between the brush and the pad-roll. l

6. In a drying-machine, the comb nation of a frame, a rotary brush supported in said frame, a swinging frame mounted in the brush frame, brackets on said swingin frame, a detachable absorbent pad r0 mounted in said brackets, and means to support a rinting-plate between the brush and the pa -roll.

In testimony whereof I have hereunto set my hand this 30th day of December, A. D. 1905.
